Test conditions and notes4

1. All parameters NOT specially mentioned are measured at 800Vdc input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μf & 47μf parallel capacitor.
3. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on http://www.meanwell.com)

FAQ

Can the DDRH-30-15DR power 15V industrial analog instruments or signal conditioning equipment?

Yes. The DDRH-30-15DR provides 30W at 15V and 2A, which suits analog instrumentation, signal conditioning modules, and some industrial transmitters that require a 15V supply. Its DIN rail mounting allows it to be installed directly in the same panel as the instruments it powers.

Is the DDRH-30-15DR suitable for powering 15V stepper motor drivers or small motion control modules?

Yes. Compact stepper motor drivers and low-power motion control modules that operate at 15V can be supplied by the DDRH-30-15DR at 30W and 2A. The 10:1 ultra-wide input (150–1500VDC) allows it to interface with high-voltage DC buses common in motion control infrastructure.

Can this unit supply 15V logic rails in an embedded industrial control system?

Yes. The DDRH-30-15DR can provide a regulated 15V logic rail for embedded industrial controllers, DSP boards, or FPGAs that require this voltage. Its DIN rail-mount design fits well in compact control enclosures where panel space is a priority.

What are the environmental operating limits of the DDRH-30-15DR?

The DDRH-30-15DR operates from -40°C to +80°C (with load derating at higher ambient temperatures per the derating curve), covering both cold storage and high-ambient industrial environments. No IP rating is provided for the unit itself, so enclosure-level protection is required when installing in locations exposed to moisture, dust, or contaminants.

How do the DDRH-30-15DR, DDRH-30-15P, and DDRH-30-15ST compare?

All three variants provide 30W, 15V, and 2A output with a 150–1500VDC input range and the same IEC62109-1 (LVD) and EAC TP TC 004 approvals. The DDRH-30-15DR is DIN rail-mount, the DDRH-30-15P is PCB-mount, and the DDRH-30-15ST uses screw terminal connections. Select the variant based on the mounting and wiring method required for the application.
